KEYSERLINGELLA. 
Keyserlingella, Peckham, Occas. Papers Nat. Hist. Soc. Wisc. ii. 1, p. 69 (1892). 
Type K. perdita, Peckham. Colombia. 
The full diagnosis of this genus cannot be given without examples for examination. 
The following characters are those mentioned by Peckham :—Spiders small. 
Cephalothorax almost flat above, without constriction or depression. Quadrangle of 
eyes wider than long, equally wide in front and behind, or wider behind, occupying at 
least one-half of the cephalothorax. Mandibles vertical or slightly inclined. Legs 
(3) 4,1, 38,2; (2) 4, 3,1, 2.

PARADAMCETAS. 
Paradametas, Peckham, Proc. Wisc. Acad. Sci. 1885, p. 78 (Dec.). 
Type P. formicina, Peckham. Guatemala. 
Characters based on the female. Legs i. and ii. incrassate, especially the femora. Legs 4, 3, 1, 2, or 4, 1,3, 2. 
Tibia i. with 2—2—2 spines ; protarsus i. with 2—2 spines beneath. Palpi slender. Sternum about 
one-fourth longer than broad. Coxa iv. longer than that of i., ii., and ili. ; trochanter iv. not more than 
half the length of coxa iv. Anterior eyes in an almost straight line, straight by the posterior margins: 
diameter of laterals scarcely more than half that of centrals. Mandibles vertical, weak. Cephalic 
quadrangle broader than long, slightly wider behind, occupying less than half the total length of 
the carapace. Abdominal pedicle very short. Small eyes equidistant between the anterior and posterior 
laterals.

Hab. GuateMaLta!; Panama, Bugaba (Champion). 
The female from Bugaba differs so little in the form of the vulva from the figure 
given by Peckham that one cannot but regard it as belonging to the same species. 
Subfam. SAL TICINA. 
The members of this subfamily differ from those of the Toxeinz in not possessing a 
definite elongated pedicle between the carapace and the abdomen. ‘The legs are much 
stouter as a rule and much more spinose. The genera belonging to this division which 
are represented in Central America may be separated into various more or less definite 
and natural groups. The Lyssomaneze and the Homalatteze are perhaps as distinct as
